I am currently working on a project migrating a news website built with php and mysql (originally hosted on AWS) to google cloud platform, I have come up with the following architecture:
Web servers :2 vm instances (with websever + php) on GCE with an https load balancer in front
Database : google cloud sql : 1 master instance + 1 failover replica + 1 read replica.
My questions are as follows:
1. the customer used memcache/redis (originally use AWS elasticcache), does that mean I have to either install redis on a GCE vm or use GAE's built i memcache?
2. the customer used AWS Cloudsearch, but there is no equivalent GCP service, does that mean i have to install a customized solution
3. Do i have to configure a load balancer for reading from google cloud sql replicas? how do i separate write to the master and read to the read replica? Do I have to do some special configuration, or the Google cloud sql will manage and distribute the write/read operation to the correct instances (master vs read replica)
4. the customer is currently using AWS WAF, is there any equivalent GCP service?
Any suggestions? Your kind help will be deeply appreciated.
